Abstract Abstract. Vertical Displacement Events (VDEs) and plasma current disruptions can seriously degrade the lifetime of in-vessel components in ITER, as large electromagnetic and thermal loads can be induced at such events. Hence, accurate modelling of such events is crucial for estimating disruption induced forces. In the past, ITER disruption modelling has been carried out using the DINA code. However, since predictive simulation of such events depend on a large number of model assumptions, the resultant predictions may contain significant error bars. It is important therefore to validate the code results with other models. With such an objective in mind, we have carried out VDE and Disruption simulations using the Tokamak Simulation Code (TSC) and the results are compared with the earlier DINA predictions. The two model predictions match reasonably well, especially in the early linear part of the vertical evolution, though there are some differences in the phase dominated by halo currents. 1.
